Application inea April 21, 1327. serial No. 1se,s14.

My invention relates to rotary coolers 'which are particularly suitable for material entering'the'dryer at a high-temperature, which affects the expansion and contraction of the cooler. This cooler is an improvement over Patent No. 1,617,815, from which it differs in the provision of means for per- `mitting the tubes that carry the coo ing medium to expand and contract relative. to

l the body of the cooler.

In the appended drawing, Figure 1 is a longitudinal broken vrsection on line 1--1,

Figure 2, and

Figure 2 is a transverse section on llne l5 Q-2, Figure 1.

In the drawing, 3 represents the drum of Athe cooler which is provided at the ends with.'

Aheads 4 and 5, respectively. To the head 4 are anchored. the series of tubes 6 -through 2" which the cooling medium is to be circulated.-

The other ends of the tubes project through the head 5 into a stationary houslng 7 located in proximity to the head `5. The housing 7 is provided lwith 'suitable aperture 8.to a'ccommodate the loading hopper -9 through whichvthe material to be cooled may be discharged into the` cooler through' the head 5.`

Each ofthe tubes entering the housing 7 is provided with avalve 10 and a nozzle 11.

Only two are shown in Figure 2, the rest are omitted. Each nozzle isV inclined from -the vertical plane and also away fromr-the direction of rotation so as to reduce the 'splashing of the cooling medium discharged by each of the tubes.

The cooling medium is suppliedrto the:

tubes` through the head 4'by a manifold 12.

` The manifold is connected to an axial re` volving pipe 13 which carries a `stuiiing box 40 14 connectedwithv a stationary .supply pipe 15. The material from the cooler 1s discharged through the central part of the head 4 to a stationary casing 16 through which the pipe 13 projects. It therefore will be noted that the flow of the material and that of the cooling medium are in opposite directions.

' i To further reduce the splashing of lthe cooling medium lin thehousing 7, a semicircular concave trough 17 is formed in the housing below the aperture'` 8 for the loading hopper 9. AThis trough 17 receives the cooling medium which is discharged by the nozzles above or runs on the walls forming the Iaperture 8 and also whatever is reilected i by the outer wall 18 of the housing 7 into the .part of the housing 7. This trough 19 )oins said hopper or the wall above it. In addi' tion, the I housing 7 has an upper semicircular convex trough 19, which is formed about the outer row of tubes 6 in the upper the outer wall 18 of the vhousing 7' by'an l inclined peripheral wall 20 which directs any i cooling medium that tends to rise towthe periphery of the upper half of the housing 7 vinto the4 trough 19, which therefore will., cause the coolingl medium entering theretoA to fall into they lower art of the housing7 without striking any of) the discharge nozzles rand valves of the tubes 6 directly below it. At the lower part of the stationary housingv 7 there is a main discharge 20 anda secondary discharge 21 leading from the lower part of the semi-circular trough 17 to the discharge 20, as best seen in Flgure 1. v By providing the stationary housing with the upper and'lower trou hs,.the'splashng' of the cooling medium wi in the housing is ,Y reduced to a minimum and therefore the inleakage of the cooling` medium along the tubes `6 through the head 5 into the cooler is also prevented. If desired, suitable packing glands may be rovided in the head 5 for the 'tubes 6, w ich will prevent any inleakage, but will ermit a free expansion and contraction of t e tubes 6 in the cooler.

I claim- 1. In a. cooler, a plurality of tubes for carrying a cooling medium, said tubes being anchored at one end and free to move longitudinally at the other, a housin receiving the free end of the tubes, means Ier supplying the anchored ends of the tubes with the cooling medium and means at the free ends of the tubes for controlling and directing the discharge of thecooling medium into the housing. v l

2. In acooler, a pluralityof tubes, one end of which is anchored and theother isrfree vto move longitudinally 'under the expansion and contraction, means for supplying cooling medium to the anchored ends of the ltu es, means for controlling and directing the discharge ofthe cooling medium4 from the tubes at the free end thereof, a housing receiving the-free ends of Ythe which the cooling medium is dischar d vand means carried by said housing to uce the splashing therein of the discharged cooling `medium. ff tubes into of each tube of which is anchored and the other isfree to move longitudinally, means for supplying cooling medium to the anchored ends of the tubes, nozzles at the free ends of the tubes for directing the flow of the cooling medium in a predetermined direction, a housing receiving said nozzles and means within said housing adapted to prevent the upper nozzles from discharging onto the lower nozzles. 4

4. In a cooler, a plurality of tubes disosed circumferentially for carrying n coollng lnedium, said'tubes'being anchored4 at one end and free to move vlongitudinally at the other, a housing receiving the free ends of the tubes, means for supplying the anchored ends of the tubes with cooling medium, means, at the free ends of the tubes for controlling the discharge of the cooling medium and a concave trough within the circumference of the tubes for receiving some of the cooling medium within the housing; 5.. In a cooler, a plurality of tubes disposed circumferentially, said tubes being anchored at one end and free to move longitudinally at' the other, a housing receiving the free ends of the tubes, .means for supplying the anchored ends of the tubes with J umane cooling medium, means at the free end of the tubes for controlling the discharge of the cooling medium, a trou h within the circumference of the tubes an a trou" h out of the circumference of the tubes some of the cooling medium discharged into the housing to reduCeJsPIaShin therein.

6. In a cooler, a. plurality o? .tubes disposed circumferentially, and adapted to rotate, said tubes being anchored lat oney end and free to move longitudinally at the other, astationary housing receiving the free ends of the tubes, means Vfor supplying the anchored ends of the tubes with coollng medium, means at the free ends of the tubes for controlling the discharge of the cooling me,

dium into the stationary housing, a concave trough carried by the housing within vthe circumference of the tubes for receiving some of the cooling medium discharged into the housing, a convex trough carried by the housing in the upper part thereof outside of the circumference of theztubes also for receiving some of the coolin medium discharged into the housingan means for removing the cooling medium from the housing.
